Minimally invasive thoracic surgery for empyema

Abstract

The widely accepted and still increasing use of video-assisted thoracic surgery (VATS) in pleuro-pulmonary pathology imposes the need to deal with two major pitfalls: the first is to avoid its unselective use, while the second relates to inappropriate rejection of VATS on the basis of “insufficient radicality”. Unlike a quite established role of VATS in lung cancer patients, in patients with pleural empyema, the role of VATS is less clearly defined. The current evidence about VATS in patients with pleural empyema could be summarised as follows: VATS is accepted as a useful treatment option for fibrinopurulent empyema, but the treatment failure rate increases with the increasing proportion of stage III empyema, necessitating further surgical options like thoracotomy and decortication. As both pulmonologists and surgeons deal with diagnosis and treatment of pleural empyema, this article is an attempt to highlight the existing evidence in a more user-friendly way in order to help practising physicians to optimise the use of VATS in these patients. In other words, in the absence of randomised studies comparing VATS and thoracotomy, the key question to be answered is: are there any pre-operative findings that can be used to select patients for initial VATS versus proceeding directly to a thoracotomy?
